I called Kia and they said I would have to come in to get a diagnostic test for $107 , although I told them it seems to be the key ignition. …”

“The gear shifter is freely allowed to move, yet the electrical system is registering that the car hasn't left neutral. (example: when I place the car in p(ark), the display above the odometer will remain in n(eutral). The shifter is freely allowed to move when the car is on and the brake is pressed down as usual.”
